Quadratus Femoris

Quadratus Femoris The structure indicated is the quadratus femoris muscle. The quadratus femoris muscle is one of the muscles of the gluteal region. The muscles in the gluteal region are divided into a superficial and deep group. There are four muscles of the superficial group: Gluteus maximus Gluteus medius Gluteus minimus Tensor fasciae latae There are 5 muscles in the deep group: Gemellus superior Gemellus inferior Quadratus femoris Piriformis Obturator internus The deep muscles of the thigh are much smaller than the superficial group of muscles and generally serve to laterally rotate the femur at the hip joint. The quadratus …

Talus

Talus The structure indicated is the talus bone of the foot. The foot contains three groups of bones: Tarsals Metatarsals Phalanges The talus is one of seven tarsal bones. There are three groups of tarsal bones: Proximal group Intermediate group Distal group There are two bones in the proximal group of tarsal bones: the talus and the calcaneus. The calcaneus is the largest tarsal bone and forms the heel through its posterior projection. The talus articulates with the medial malleolus of the tibia and the lateral malleolus of the fibula to form the ankle joint. In addition, it articulates with …

Cuboid Bone

Cuboid Bone The structure indicated is the cuboid bone of the foot. The foot contains three groups of bones: Tarsals Metatarsals Phalanges The cuboid bone is one of seven tarsal bones. There are three groups of tarsal bones: Proximal group Intermediate group Distal group The cuboid bone belongs to the distal group of tarsal bones. There are four bones in the distal group: Lateral cuneiform Intermediate cuneiform Medial cuneiform Cuboid The cuboid bone is the most lateral bone in the distal row of tarsal bones, it is named on the basis of its shape which roughly resembles a cube. The …

Rectus Femoris

Rectus Femoris The structure indicated is the rectus femoris of the quadriceps group of thigh muscles. The rectus femoris is one of the muscles that makes up the quadriceps femoris, and is contained in the anterior compartment of the thigh. The muscles of the anterior compartment are all innervated by the femoral nerve and serve generally to extend the leg at the knee joint. The four muscles that make up the quadriceps femoris are the: Rectus femoris Vastus lateralis Vastus medialis Vastus intermedius In addition to the quadriceps muscles, the Sartorius muscle is also located in the anterior compartment together …

Gemellus Superior

Gemellus Superior The structure indicated is the gemellus superior. The gemellus superior muscle is one of the muscles of the gluteal region. The muscles in the gluteal region are divided into a superficial and deep group. There are four muscles of the superficial group: Gluteus maximus Gluteus medius Gluteus minimus Tensor fasciae latae There are 5 muscles in the deep group: Gemellus superior Gemellus inferior Quadratus femoris Piriformis Obturator internus The word gemellus comes from the Latin “gemelli” which means “twins”. There are therefore two gemelli muscles, the gemellus superior, and the gemellus inferior. The gemelli muscles are located either …
